DESCRIPTION OF EMBODIMENTS

The technical solutions in embodiments of this application are clearly described in detail below with reference to the accompanying drawings. In the descriptions of embodiments of this application, unless otherwise stated, “/” represents the meaning of “or”. For example, A/B may represent A or B. “And/or” in the text merely describes an association relationship between associated objects and represents that three relationships may exist. For example, A and/or B may represent the following three cases: Only A exists, both A and B exist, and only B exists. In addition, in the descriptions of embodiments of this application, “a plurality of” means two or more than two.

Hereinafter, the terms “first” and “second” are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating a quantity of indicated technical features. Therefore, a feature limited by “first” and “second” may explicitly or implicitly include one or more features. In the descriptions of embodiments of this application, unless otherwise stated, “a plurality of” means two or more.

A term “user interface (UI)” in the following embodiments of this application is a medium interface for interaction and information exchange between an application or an operating system and a user, and implements conversion between an internal form of information and a form acceptable to the user. The user interface is source code written in a specific computer language such as Java or an extensible markup language (XML). Interface source code is parsed and rendered on an electronic device, and is finally presented as content that can be recognized by the user. The user interface is usually represented in a form of a graphical user interface (GUI), and is a user interface that is related to a computer operation and that is displayed in a graphic manner. The user interface may be a visual interface element such as a text, an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, or a Widget that is displayed on a display of the electronic device.

For ease of understanding the solutions provided in embodiments of this application, the following describes related concepts in embodiments of this application.

Screen lock may be locking a screen of an electronic device, to prevent false touch, accidental touch, or others from using the electronic device of the user. In a screen-locked and screen-off state, the user cannot use the electronic device, or, if audio content is played before the screen is locked, the user can only listen to the audio content; or, in a screen-locked and screen-on state, the user can only browse some information or enable specific functions such as the camera and flashlight. The electronic device needs to be unlocked by using an unlocking manner set by the user, so that the user can normally use the electronic device. The screen-locked and screen-off state may also be referred to as a screen-locked and screen-off state, and the screen-locked and screen-on state may also be referred to as a screen-locked and screen-on state.

The screen-locked and screen-off state may mean that, in response to a screen lock operation, the electronic device switches to a state in which the screen is locked and the screen is turned off. The screen lock operation may include but is not limited to: a press operation on a screen lock button on a side edge or a top edge of the electronic device, a tap operation on a screen lock control in a user interface, a voice instruction, a gesture instruction, and the like.

The screen-locked and screen-on state may mean that, when the electronic device is in the screen-locked and screen-off state, in response to a screen-on operation, the electronic device switches to a state in which the screen is locked and the screen is lit up. The screen-on operation may include but is not limited to: an operation of double tapping the screen, an operation of lifting the electronic device, and the like. In some implementations, the electronic device may set duration of the screen-locked and screen-on state in response to a user operation. Specifically, in response to the screen-on operation, the electronic device switches to the screen-locked and screen-on state and lasts for specific time (for example, 10 s). Then, the electronic device switches to the screen-locked and screen-off state.

An unlocked and screen-on state may mean that, when the electronic device is in the screen-locked and screen-off state or the screen-locked and screen-on state, in response to an unlock operation, the electronic device switches to a state in which the screen is unlocked and the screen is lit up. The unlock operation may include but is not limited to: a touch operation on a specific area (such as a fingerprint recognition area), a face unlock operation facing the camera, an operation of entering a password (such as an alphabetic and/or numeric password or a graphic password), and the like. In a possible implementation, the first two operations mentioned above can be implemented when the electronic device is in the screen-locked and screen-off state or the screen-locked and screen-on state, and the last operation can be implemented only when the electronic device is in the screen-locked and screen-on state.

A wallpaper may be a picture displayed on an entire screen of the electronic device. Wallpapers may include a screen lock wallpaper, a desktop wallpaper, a screen-off wallpaper, and an interactive wallpaper. The wallpaper may include pictures preset by the electronic device, and may also include pictures stored in an album of the electronic device.

The screen lock wallpaper may be displayed when the electronic device is in the screen-locked and screen-on state, the desktop wallpaper may be displayed when the electronic device is in the unlocked and screen-on state, the screen-off wallpaper may be displayed when the electronic device is in the screen-locked and screen-off state, and the interactive wallpaper may also be displayed when the electronic device is in the screen-locked and screen-off state. It should be noted that the electronic device may display the screen-off wallpaper when the always on display (AOD) function is enabled. The AOD function is a function of the electronic device to display time, date, icons and other information in some areas of the screen without lighting up the entire screen (that is, the electronic device maintains low power consumption). However, the foregoing interactive wallpaper in this application is the wallpaper displayed on the main screen and/or the entire back screen under the premise that the electronic device lights up the entire main screen and/or the entire back screen, and the current electronic device is not in a low power consumption state. In other words, a display mechanism of the screen-off wallpaper is different from that of the interactive wallpaper.

The following first describes a structural form of the electronic device provided in this embodiment of this application.

The electronic device provided in this embodiment of this application is an electronic device with an outward foldable screen. The outward foldable screen may mean that the user can observe the screen after folding, that is, the screen after folding faces outward. A screen after an inward foldable screen is folded faces inward and is hidden, and the user cannot observe the screen after folding.

A main screen and a side area of an electronic device with an outward foldable screen may be connected by using a first folding component, and a back screen and the side area of the electronic device with the outward foldable screen may be connected by using a second folding component.

FIG. 1A shows an example of a structural form of an electronic device in an unfolded state.

As shown in FIG. 1A, the electronic device may include but is not limited to: a back screen 201, a main screen 202, and a side area 203. The back screen 201, the main screen 202, and the side area 203 may be referred to as an entire screen. When the electronic device is in the unfolded state, an angle between the back screen 201 and the main screen 202 may be 180 degrees or approximately 180 degrees. The entire screen of the electronic device faces a same direction as the back screen 201 and the main screen 202. To be specific, the main screen and the back screen that are shown in FIG. 1A face a same direction. Further, the main screen, the side area, and the back screen all face the same direction.

When a user faces the entire screen, a display area that can be observed by the user is the entire screen. In a possible implementation, a back surface of a plane in which the entire screen in the electronic device is located does not include a display. In another possible implementation, the back surface of the plane in which the entire screen in the electronic device is located includes a display. In this embodiment of this application, an example in which the back surface of the plane in which the entire screen in the electronic device is located does not include a display is used for description.

FIG. 1B shows an example of a structural form of an electronic device in a folded state.

As shown in FIG. 1B, (a) and (b) are structural forms of the electronic device in the folded state that are observed from different directions. (a) is a diagram of a structural form of the electronic device observed from the back surface, and (b) is a diagram of a structural form of the electronic device observed from the front surface. In this embodiment of this application, the front surface and the back surface are only examples for description, and only indicate that an observation angle between the two is 180 degrees. This is not limited herein.

The electronic device may include but is not limited to: a back screen 211, a main screen 212, and a side area 213. When the electronic device is in the folded state, an angle between the back screen 201 and the main screen 202 may be 0 degrees or approximately 0 degrees. Optionally, the electronic device may further include a camera 214, where the camera 214 and the back screen 211 are located on a same surface in the folded state. An orientation of the camera 214 does not change as the electronic device is folded or unfolded.

In (a), the orientation of the back screen and the orientation of the main screen are shown in (a). When facing the back screen 211, the user can observe the back screen 211, but cannot observe the main screen. In (b), the orientation of the back screen and the orientation of the main screen are shown in (b). When facing the main screen 212, the user can observe the main screen 212, but cannot observe the back screen. In other words, when the electronic device is in the folded state, the main screen and the back screen face opposite directions, and an angle between the orientation of the side area and the orientation of the main screen is 90 degrees or approximately 90 degrees, and an angle between the orientation of the side area and the orientation of the back screen is also 90 degrees or approximately 90 degrees.

In this embodiment of this application, the structural forms of the electronic device shown in FIG. 1A and FIG. 1B are described only by using examples, and the electronic device may further include more or fewer structures. This is not limited herein.

In some implementations, in the screen-locked and screen-on state, the electronic device may display a screen lock wallpaper on the back screen and/or the main screen. In the unlocked and screen-on state, the electronic device may also display a desktop wallpaper on the back screen and/or the main screen.

In this embodiment of this application, after switching to the screen-locked and screen-off state, the electronic device may display the interactive wallpaper on the back screen, where the interactive wallpaper is different from the screen lock wallpaper and the desktop wallpaper. In other words, when the electronic device sets the screen lock wallpaper and the desktop wallpaper, the electronic device may also be provided with the interactive wallpaper.

With reference to user interfaces, the following describes a method for displaying an interactive wallpaper according to an embodiment of this application.

FIG. 2A to FIG. 2F show related user interfaces for setting an interactive wallpaper according to an embodiment of this application.

As shown in FIG. 2A, a user interface 200 is a user interface provided for a setting application of the electronic device. The electronic device may display a user interface 200 in response to an operation of the user on a setting icon in the desktop. The user interface 200 may include a plurality of function bars, such as a foldable screen zone bar 204. In response to a tap operation on the foldable screen zone bar 204, the electronic device may display a user interface 210 shown in FIG. 2B.

As shown in FIG. 2B, the user interface 210 is a user interface used by the electronic device to set a foldable screen related function. The user interface 210 may include but is not limited to an application scaling control 214, an application split-screen control 215, and a chroma glow pack control 216. Optionally, the user interface 210 may further include a personalized back screen and a side display control, where the electronic device may set a back screen lock wallpaper in response to an operation on the personalized back screen and the side display control. This is not described in detail in this embodiment of this application. As shown in FIG. 2B, the electronic device may display a user interface 220 in response to a tap operation on the chroma glow pack control 216.

As shown in FIG. 2C, the user interface 220 is a user interface provided by the electronic device for setting chroma glow pack. The chroma glow pack may be understood as the foregoing interactive wallpaper. The user interface 220 may include but is not limited to a back screen preview area 221, a style change control 222, a slide control 223, a display duration control 224, and a card add control 225.

The back screen preview area 221 may be used to display a style of the interactive wallpaper set by the electronic device for the back screen, for the user to preview the style. In a possible implementation, if the user has set the interactive wallpaper before tapping the chroma glow pack control 216, when the user interface 220 is displayed in response to the operation of tapping the chroma glow pack control 216 by the user, the back screen preview area 221 may display the style of the previously set interactive wallpaper.

The electronic device may enable or disable an interactive wallpaper display function in response to a tap operation on the slide control 223. Enable of the interactive wallpaper display function may mean that the electronic device may display the interactive wallpaper based on set display duration after switching to the screen-locked and screen-off state, or may receive an operation of the user on the back screen when the interactive wallpaper is displayed, to change the style of the displayed interactive wallpaper. Optionally, when the interactive wallpaper display function is enabled, the electronic device may further display prompt information, where the prompt information is used to inform the user that if the interactive wallpaper display function is enabled, the interactive wallpaper is displayed each time after the screen is turned off, but power consumption and heat generation of the electronic device are increased to some extent, to further determine whether the user determines to enable the function. Disable of the interactive wallpaper display function may mean that the electronic device does not display the interactive wallpaper after switching to the screen-locked and screen-off state. If the user sets to enable the AOD, the AOD is displayed after the user switches to the screen-locked and screen-off state. If the user sets to disable the AOD, after switching to the screen-locked and screen-off state, the electronic device keeps screen-off, and content is not displayed. A manner of setting to enable or disable the AOD is described in detail below.

The display duration control 224 may be used to set duration in which the interactive wallpaper is displayed. For example, the electronic device may display a user interface 230 in response to a tap operation on the duration display control 224. In a possible implementation, the electronic device may preset duration (for example, 5 minutes) in which the interactive wallpaper is displayed and a condition for displaying the interactive wallpaper (for example, power is not less than 20%). In this embodiment of this application, the electronic device may preset other display duration and display conditions. This is not limited. As shown in FIG. 2D, the user interface 230 is a user interface provided by the electronic device for setting chroma glow pack display duration. The user interface 230 may include but is not limited to: a plurality of duration controls, such as a duration control 231, and a cancel control 232. For example, in response to a tap operation on the duration control 231, the electronic device may set duration in which the interactive wallpaper is displayed to 5 minutes. In other words, after displaying the interactive wallpaper for 5 minutes, the electronic device no longer displays the interactive wallpaper, and may display a black screen or a turned-off screen until the electronic device switches to the screen-locked and screen-off state from another state next time, and displays the interactive wallpaper for 5 minutes again. The cancel control 232 may indicate to cancel the display duration set this time, and display the interactive wallpaper based on the previously set display duration.

The card add control 225 is used to add a “chroma glow pack” card to the desktop. The electronic device may display the following user interface 400 in response to an operation on the card add control 225. Details of the user interface 400 are not described herein.

The electronic device may display a user interface 240 in response to a tap operation on the style change control 222.

As shown in FIG. 2E, the user interface 240 is a user interface provided by the electronic device for setting chroma glow pack styles. The user interface 240 may include but is not limited to: a style 241, a style 242, a style 243, and a back screen preview area 245. The back screen preview area 245 is used to preview the style of the set interactive wallpaper displayed on the back screen. For example, during first use by the user, the style is not determined currently, and no specific style is displayed on the back screen preview area 245. As described above, if the interactive wallpaper is set previously, the style of the previously set interactive wallpaper is displayed. After the user selects a new interactive wallpaper, the style of the interactive wallpaper displayed in the preview area is updated in response to a selection operation of the user.

Optionally, the electronic device may display more styles in response to an upward-slide operation on a “pack selection” area at the lower part of the user interface 240.

Optionally, the user interface 240 of the electronic device may further include a control 244. For example, the control 244 display text content “flip to display the main screen”. In response to a tap operation on the control 244, the electronic device may display a user interface 250 shown in FIG. 2F, and set the style of the interactive wallpaper displayed on the main screen.

For example, the style 241 is a handbag style, the style 241 may include but is not limited to an icon 241A, an icon 241B, an icon 241C, an icon 241D, an icon 241E, and an icon 241F, and the style 241 may further include a chain 241G. The icon 241A may indicate an add-to-favorites function in a system application, the icon 241B may indicate a social application, the icon 241C may indicate a camera application, the icon 241D may indicate a clock application, the icon 241E may indicate a sports application, and the icon 241F may indicate a music application. In this embodiment of this application, the electronic device may change icons included in the style 1 in response to a user operation, for example, an icon indicating a weather application and an icon indicating a note application. This is not limited.

The style 242 is a panda style, where the panda is posed with both hands raised, both legs curled inward, and the mouth corners upward.

The style 243 is a feather style, and the feathers are spread out naturally in posture.

Optionally, the electronic device may further include more styles. For example, a water flow style, a multi-ball style, a color change style, and the like. This is not limited.

In the user interface 240, the electronic device may set the interactive wallpaper of the back screen to the wallpaper of the style 241 or the wallpaper of the style 242 or the wallpaper of the style 243 in response to a tap operation on the style 241, the style 242, or the style 243. After the interactive wallpaper of the back screen is set, the electronic device may display the wallpaper of the style 241 or the wallpaper of the style 242, or the wallpaper of the style 243 in the back screen preview area 245. In the user interface 250, the electronic device may set the interactive wallpaper of the main screen to the wallpaper of the style 241 or the wallpaper of the style 242 or the wallpaper of the style 243 in response to a tap operation on the style 241, the style 242, or the style 243. After the interactive wallpaper of the main screen is set, the electronic device may display the wallpaper of the style 241 or the wallpaper of the style 242, or the wallpaper of the style 243 in the main screen preview area 255.

For example, in response to a double tap operation on the style 241 or the style 242 or the style 243, the electronic device may further cancel setting the interactive wallpaper to the wallpaper of the style 241 or the wallpaper of the style 242 or the wallpaper of the style 243. After the electronic device cancels setting the interactive wallpaper, in this case, the electronic device may be considered to be in a state in which the interactive wallpaper is not set on the back screen.

The electronic device may set corresponding interactive wallpapers on both the main screen and the back screen in response to a user operation, or set an interactive wallpaper only on the main screen, or set an interactive wallpaper only on the back screen. When the corresponding interactive wallpapers are set on both the main screen and the back screen, the interactive wallpaper set on the main screen may be the same as or different from the interactive wallpaper on the back screen. This is not limited in this application. In a possible implementation, upper areas of the user interface 240 and the user interface 250 may further include a check control, where the check control is used to set whether to validate the set interactive wallpaper on the corresponding screen.

For example, in the user interface 240, in response to an operation of selecting the check control by the user, the electronic device may determine (that the always on display function in the user interface 220 shown in FIG. 2C is enabled), and displays the interactive wallpaper on the back screen when the screen is turned off. In the user interface 240, in response to an operation of deselecting the check control by the user, the electronic device may determine (that the always on display function in the user interface 220 shown in FIG. 2C is enabled), and does not display the interactive wallpaper on the back screen when the screen is turned off. Similarly, in the user interface 250, in response to an operation of selecting the check control by the user, the electronic device may determine (that the always on display function in the user interface 220 shown in FIG. 2C is enabled), and display the interactive wallpaper on the main screen when the screen is turned off. In the user interface 250, in response to an operation of deselecting the check control by the user, the electronic device may determine (that the always on display function in the user interface 220 shown in FIG. 2C is enabled), and does display the interactive wallpaper on the main screen when the screen is turned off. The check controls of the user interface 240 and the user interface 250 may be both selected, or one of the check controls of the user interface 240 and the user interface 250 is selected. This is not limited in this application. It should be noted that, if the always on display function in the user interface 220 shown in FIG. 2C is disabled, regardless of whether the check controls of the user interface 240 and the user interface 250 are selected, the electronic device does not display the interactive wallpaper on the main screen or the back screen when the screen is turned off.

Based on the foregoing user settings, the electronic device may display interactive wallpapers of a same style on the main screen and/or the back screen in response to a user operation; and the electronic device may also display interactive wallpapers of different styles on the main screen and/or the back screen in response to a user operation. In this way, the electronic device may display the interactive wallpaper only on the main screen in response to a user operation. Optionally, the electronic device may determine, by determining whether the screen faces upward, whether to display the interactive wallpaper on the main screen or display the interactive wallpaper on the back screen.

For example, the electronic device may display a user interface 250 in response to a tap operation on the control 244. The user interface 240 is a user interface provided by the electronic device for setting chroma glow pack styles. Similarly, the user interface 250 may include a style 251, a style 252, and style 253, and a main screen preview area 255. The main screen preview area 255 is used to preview the style of the currently set interactive wallpaper displayed on the main screen. For example, the style of the interactive wallpaper is not determined currently, and no specific style is displayed in the main screen preview area 255. Optionally, the electronic device may display more styles in response to an upward-slide operation on a “pack selection” area.

Optionally, the electronic device may further include a control 254. The control 254 indicates to set the interactive wallpaper displayed on the back screen. For example, the control 254 display text content “flip to display the back screen”. For example, the electronic device may display a user interface 240 in response to an operation of the user on the control 254.

In response to a tap operation on the style 251 or the style 252 or the style 253, the electronic device may set the interactive wallpaper displayed on the main screen to the wallpaper of the style 251 or the wallpaper of the style 252 or the wallpaper of the style 253. The wallpaper of the style 251 or the wallpaper of the style 252 or the wallpaper of the style 253 may be displayed in the main screen preview area 255 after the interactive wallpaper is set. For example, in response to a double tap operation on the style 251 or the style 252 or the style 253, the electronic device may further cancel setting the interactive wallpaper to the wallpaper of the style 251 or the wallpaper of the style 252 or the wallpaper of the style 253. After the electronic device cancels setting the interactive wallpaper, in this case, the electronic device may be considered to be in a state in which the interactive wallpaper is not set on the main screen.

FIG. 4A to FIG. 4J show related user interfaces for setting an interactive wallpaper according to an embodiment of this application.

For example, the electronic device may set the interactive wallpaper to the wallpaper of the style 241 in response to a tap operation on the style 241. Subsequently, the electronic device may return to displaying the user interface 220 in response to an operation of tapping a return control by the user. In this case, the wallpaper of the style 241 is displayed in the back screen preview area 245 of the user interface 220. In some implementations, after detecting, in the user interface 220, that the interactive wallpaper of the style 241 is set, the electronic device may automatically display pop-up information, namely, display a user interface 400. In another possible implementation, the electronic device may display a user interface 400 in response to a tap operation on the card add control 225 in the user interface 220.

As shown in FIG. 4A, the user interface 400 may include but is not limited to a back screen preview area 401, a style change control 402, and a prompt box 403. A style of the currently selected interactive wallpaper, for example, the style 241, is displayed in the back screen preview area 401. The prompt box 403 may include prompt information 403A, a card 403B, a check control 403C, a cancel control 403D, and an add control 403E. For example, the prompt information 403A displays text information “Do you want to add the “chroma glow pack” card to the desktop?”. The card 403B may include a card name 403F, a preview wallpaper 403G, and a control 403H. The card name 403F displays the text information “chroma glow pack”. Content displayed in the preview wallpaper 403G is consistent with content displayed in the back screen preview area 401, but sizes are different. The control 403H indicates that the electronic device can enter the screen-locked and screen-off state. The check control 403C may indicate that after the style of the interactive wallpaper is changed next time, the prompt box 403 is not displayed, and the setting of adding or not adding the card 403B this time is still used by default. The electronic device may cancel adding the card 403B in response to a tap operation on the cancel control 403D. The electronic device may also add the card 403B to the desktop in response to a tap operation on the add control 403E. After adding the card 403B, the electronic device may display a user interface 410 in response to a user operation.

In a possible implementation, the electronic device may automatically add the “chroma glow pack” card. For example, after detecting, in the user interface 220, that the interactive wallpaper of the style 241 is set, the electronic device may automatically display pop-up information, namely, display a user interface 410.

As shown in FIG. 4B, the user interface 410 may include a back screen preview area 411, a style change control 412, and a prompt box 413. The prompt box 413 may include prompt information 413A, a card 413B, a check control 413C, and a control 413D. For example, the prompt information 413A displays text information “The “chroma glow pack” card has been automatically added to the desktop”. For the card 413B, refer to the related descriptions of the card 403B. Details are not described herein. The check control 413C may indicate that the card can be automatically added next time without prompting again. The control 413D is used to close the prompt box 413. After adding the card 413B, the electronic device may display a user interface 420 in response to a user operation.

As shown in FIG. 4C, the user interface 420 is a desktop provided by the electronic device. The user interface 420 may be a desktop displayed by the electronic device in response to a leftward slide operation of the user when the main interface is displayed. In a possible implementation, the electronic device may add the card 403B or the card 413B to the main interface by default.

The user interface 420 may include but is not limited to a card 421. The card 421 is provided by a setting application, to enable a function of displaying the interactive wallpaper. Further, the card 421 may also view or change the style of the interactive wallpaper in response to a user operation. Furthermore, the card 421 may be further used to enable the electronic device to enter the screen-locked and screen-off state in response to a user operation, and display the interactive wallpaper on the main screen or the back screen. The size of the card 421 may be shown in FIG. 4C, or may be twice of the size of the card shown in FIG. 4C. The card 421 may be in a shape of a square, a rectangle, a circle, an ellipse, or the like. The background color of the card 421 may be light-colored or dark-colored. In this embodiment of this application, the size, the shape, and the background color of the card 421 are not limited.

The card 421 may include a card name 421A, a preview wallpaper 421B, and a control 421C. For example, the card name 421A displays text content “chroma glow pack”, and the preview wallpaper 421B displays the wallpaper of the style 241. The electronic device may enter the screen-locked and screen-off state in response to a tap operation on the control 421C, and display the interactive wallpaper on the main screen or the back screen.

Specifically, as shown in FIG. 2C, the always on display function in the user interface 220 is disabled, and the slide control 223 is in a closed state. The electronic device may enter the screen-locked and screen-off state in response to a tap operation on the control 421C when the function of displaying the interactive wallpaper is disabled in the setting application, and display, within duration (for example, 5 minutes or 30 s), the interactive wallpaper of the style indicated by the preview wallpaper 421B. Subsequently, after switching to the unlocked and screen-on state, in response to a screen lock operation, for example, a press operation on a screen lock button, the electronic device enters the screen-locked and screen-off state. However, because the electronic device disables, in the setting application, the function of displaying the interactive wallpaper, the electronic device cannot display the interactive wallpaper in this case. In other words, the interactive wallpaper is started only once by using the desktop card.

In this way, the user can observe the style of the interactive wallpaper more conveniently, without first enabling the function of displaying the interactive wallpaper, and then switching to the screen-locked and screen-off state to display the interactive wallpaper.

Certainly, as shown in FIG. 2C, the always on display function in the user interface 220 is enabled, and the slide control 223 is in a started state. The electronic device may also enter the screen-locked and screen-off state in response to a tap operation on the control 421C when the function of displaying the interactive wallpaper is enabled, and display, within duration (for example, 5 minutes or 30 s), the interactive wallpaper of the style indicated by the preview wallpaper 421B. The electronic device enters the screen-locked and screen-off state in response to the tap operation on the control 421C, where duration in which the interactive wallpaper is displayed may be fixed.

For example, the electronic device may enter the screen-locked and screen-off state in response to the tap operation on the control 421C, and display a user interface 430 shown in FIG. 4D on the back screen. The interactive wallpaper of the style indicated by the preview wallpaper 421B may be displayed in the user interface 430. When the electronic device enables the AOD function, the electronic device may display a user interface 440 shown in FIG. 4E after displaying the user interface 430 for a period of time. A screen-off wallpaper is displayed in the user interface 440. When the electronic device does not enable the AOD function, the electronic device controls the back screen to be turned off after displaying the user interface 430 for a period of time.

For example, when the electronic device disables, in the setting application, the function of displaying the interactive wallpaper, and starts the AOD function, the electronic device may display a user interface 460 shown in FIG. 4G in response to a screen lock operation when displaying the user interface 450 shown in FIG. 4F. The user interface 460 is consistent with the user interface 440. When the electronic device disables, in the setting application, the function of displaying the interactive wallpaper, and disables the AOD function, the electronic device may control the back screen to be turned off in response to a screen lock operation when displaying the user interface 450 shown in FIG. 4F.

In a possible implementation, when the electronic device is in the unfolded state, the electronic device cannot display the interactive wallpaper in the screen-locked and screen-off state. Refer to FIG. 4H. A user interface 470 is also a desktop provided by the electronic device. The user interface 470 also includes a card 471. The card 471 may include prompt information 471A, a preview wallpaper 471B, and a control 471C. The prompt information 471A may be used to inform the user that the function of displaying the interactive wallpaper is invalid currently, and takes effect after the electronic device is folded. For example, the prompt information 471A may display text content “Please experience after folding”. The electronic device cannot enter the screen-locked and screen-off state in response to a tap operation on the control 471C. To be specific, the current operation on the control 471C is an invalid operation. After being folded, the electronic device may display a user interface 480 shown in FIG. 4I. The user interface 480 is consistent with the user interface 420.

In another possible implementation, when power of the electronic device is less than a power threshold (for example, 20%), the electronic device cannot display the interactive wallpaper in the screen-locked and screen-off state. With reference to FIG. 4J, a user interface 490 is also a desktop provided by the electronic device. The user interface 490 also includes a card 491. The card 491 may include prompt information 491A, a preview wallpaper 491B, and a control 491C. The prompt information 491A may be used to inform the user that the function of displaying the interactive wallpaper is invalid currently, and takes effect after the power of the electronic device is greater than the power threshold. For example, the prompt information 491A may display text content “low battery”. The electronic device cannot enter the screen-locked and screen-off state in response to a tap operation on the control 491C. To be specific, the current operation on the control 491C is an invalid operation. After the power of the electronic device exceeds the power threshold, the user interface 480 may be displayed.

In this embodiment of this application, content included in the card 421 is merely an example for description, and may further include more or fewer functions. This is not limited. In addition, the position of the card 421 on the desktop is merely an example for description, and the card 421 may also be located in another desktop interface, for example, a leftmost desktop, a main interface, or the like. This is not limited.

FIG. 5A to FIG. 5I show related user interfaces for displaying an interactive wallpaper according to an embodiment of this application. In this embodiment of this application, herein, an example in which the electronic device is in the folded state and the main screen displays the user interface is used for description.

For example, the electronic device may set the interactive wallpaper to the wallpaper of the style 241 in response to a tap operation on the style 241. Then, the electronic device may display a user interface 500 on a display in response to a user operation.

As shown in FIG. 5A, the user interface 500 is a main interface provided by the electronic device. In this embodiment of this application, the user interface 500 is not limited and may be any user interface. The electronic device may switch from the unlocked and screen-on state to the screen-locked and screen-off state in response to a screen lock operation.

Once entering the screen-locked and screen-off state, the electronic device displays a user interface 510 shown in FIG. 5B. It should be noted that, duration in which the electronic device displays the user interface 510 may be display duration of the interactive wallpaper set by the user (for example, 5 minutes displayed by the duration display control 224), or may be display duration preset by the electronic device. For the user interface 510, refer to the foregoing user interface 300.

When the back screen of the electronic device displays the user interface 510, the main screen of the electronic device displays the user interface 520. As shown in FIG. 5C, the user interface 520 may include a prompt picture 521 and prompt information 522. The prompt picture 521 includes an arrow and a screen, to inform the user to flip the electronic device. The prompt information 522 may display text content “Please flip. The chroma glow pack are displayed on the back screen”. In a possible implementation, when displaying the user interface 510 on the back screen, the electronic device may further control the main screen to be turned off. To be specific, the main screen does not display the user interface 520. In this way, power consumption can be reduced.

For example, when the electronic device enables the AOD function, after displaying the user interface 510 on the back screen and displaying the user interface 520 on the main screen for a period of time, the electronic device may display a user interface 530 shown in FIG. 5D on the back screen, and display a user interface 540 shown in FIG. 5E on the main screen. When the electronic device disables the AOD function, the electronic device controls the back screen and the main screen to be turned off.

In response to a screen-on operation on the user interface 510 or the user interface 520, the electronic device may display a user interface 550 shown in FIG. 5F on the back screen, and display a user interface 560 shown in FIG. 5G on the main screen. A screen lock wallpaper is displayed on the user interface 550. A screen lock wallpaper is also displayed on the user interface 560. The screen-on operation may include but is not limited to: an operation of double tapping the screen, a press operation on a screen lock button on a side edge or a top edge of the electronic device, and the like. The user interface 560 may include a screen lock wallpaper 561, a screen lock indicator 562, and a date time indicator 563. The electronic device may display the user interface 500 in response to an unlock operation.

It should be noted that, the electronic device may switch from the screen-locked and screen-off state to the screen-locked and screen-on state. When the electronic device enables the screen lock display function of the back screen, the electronic device may display a screen lock wallpaper on the back screen after being in the screen-locked and screen-on state in the folded state. In addition, the screen lock wallpaper displayed on the back screen may be consistent with the screen lock wallpaper displayed on the main screen. For example, the wallpaper shown on the user interface 550 may also be inconsistent with the wallpaper shown on the user interface 560. When the electronic device disables the screen lock display function of the back screen, the electronic device does not display the screen lock wallpaper on the back screen, and the electronic device may control the back screen to be black.

In this embodiment of this application, when the electronic device enables the AOD function and enables the interactive wallpaper display function, the electronic device may display the interactive wallpaper with priority in the screen-locked and screen-off state. Only after the display duration of the interactive wallpaper reaches preset duration, the screen-off wallpaper can be displayed based on the set mode of displaying the AOD interface. When the electronic device does not enable the AOD function and enables the interactive wallpaper display function, the electronic device may display the interactive wallpaper in the screen-locked and screen-off state. After the display duration of the interactive wallpaper reaches preset duration, the electronic device may control the display to be turned off, that is, does not display the screen-off wallpaper. An entry for enabling the AOD function by the electronic device is inconsistent with an entry for enabling the interactive wallpaper display function. In other words, the AOD function and the interactive wallpaper are two different display functions. With reference to FIG. 5H, a user interface 570 is a user interface provided for a setting application of the electronic device. The electronic device may display a user interface 570 in response to an operation of the user on a setting icon in the desktop. The user interface 570 may include a plurality of function bars, such as a screen-off and screen lock bar 571 (or referred to as a desktop and wallpaper setting bar). The electronic device may display a user interface 580 shown in FIG. 5I in response to a tap operation on the screen-off and screen lock bar 571. As shown in FIG. 5I, the user interface 580 is a user interface used by the electronic device to set a screen-off and screen lock related function. The user interface 580 may include but is not limited to an always on display control 581. The always on display control 581 may further include prompt information. For example, the prompt information may display text content “enabled”, indicating that the electronic device has enabled the always on display function. The always on display function may also be set by tapping the control 581. For example, the always on display function is disabled, or content of the always on display function is set.

Embodiments of this application provide a method for displaying an interactive wallpaper and a related apparatus. In this method, the electronic device may set an interactive wallpaper displayed on a back screen in a screen-locked and screen-off state. Then, the electronic device displays the interactive wallpaper in the screen-locked and screen-off state. Subsequently, an operation of a user on the interactive wallpaper is detected, to change content displayed on the interactive wallpaper.

In the foregoing method, various interactive wallpapers may be disposed, to fully meet personalized requirements of users. In addition, an electronic device in a screen-locked and screen-off state may also be enabled to display an interactive wallpaper, to achieve more aesthetic affect. In addition, the user may also operate the interactive wallpaper and observe a change of the interactive wallpaper, making the process of using the electronic device more interesting for the user.

With reference to FIG. 6, the following describes a method for displaying a wallpaper according to an embodiment of this application. An execution body of the method shown in FIG. 6 may be the electronic device mentioned above. Alternatively, the execution body of the method shown in FIG. 6 may be a chip in the electronic device. This is not limited in this embodiment of this application. FIG. 6 is described by using an example in which the electronic device is the execution body of the method. The electronic device includes a display, where the display includes a main screen and a back screen. The method procedure shown in FIG. 6 is described when the electronic device is in a folded state, and when the electronic device is in the folded state, the main screen and the back screen face opposite directions. The method includes the following steps.

S601: The electronic device sets a first wallpaper to an interactive wallpaper.

The interactive wallpaper may be a wallpaper displayed on the back screen after the electronic device switches to a screen-locked and screen-off state. In addition, the interactive wallpaper may change in the form based on a user operation. The interactive wallpaper may be provided by a system application in the electronic device.

In some implementations, the electronic device may set the first wallpaper to the interactive wallpaper in response to a user operation. For example, the electronic device may enter a setting application in response to a tap operation on a setting icon, and then set the first wallpaper to the interactive wallpaper. The electronic device may also enter an interactive wallpaper setting interface in response to a tap operation on a card of the interactive wallpaper, and then set the first wallpaper to the interactive wallpaper.

Before the electronic device sets the first wallpaper to the interactive wallpaper, the electronic device may set duration in which the interactive wallpaper is displayed on the back screen, for example, 15 seconds, 30 seconds, 1 minute, or 5 minutes. Before setting the first wallpaper to the interactive wallpaper, the electronic device may preview the first wallpaper, to observe effects of first wallpapers of various styles. Optionally, the electronic device may further adjust elements included in the first wallpaper.

There may be a plurality of types of styles of the first wallpaper, for example, a wallet style, an animal style, a feather style, a water flow style, and a multi-ball style. For example, when the first wallpaper is of the wallet style, the electronic device may adjust the elements included in the first wallpaper, for example, change an icon indicating a social application to an icon indicating a weather application. In this embodiment of this application, the styles of the first wallpaper are merely examples for description, and may further include more styles. This is not limited.

The first wallpaper of each style may further include a plurality of states. First wallpapers in different states may include same elements, and forms of the same elements in the first wallpapers in different states may be different. Forms of the elements may include but are not limited to: sizes, positions, shapes, colors, movement states, and the like of the elements. For example, refer to the chain 307 in FIG. 3A and the chain 317 in FIG. 3B, the panda picture 351 in FIG. 3E and the panda picture 361 in FIG. 3F, and the feathers in the area 372 in FIG. 3G and the feathers in the area 382 in FIG. 3H.

S602: The electronic device detects a screen-locked and screen-off state.

In some implementations, the electronic device may switch from an unlocked and screen-on state to the screen-locked and screen-off state, or may switch from a screen-locked and screen-on state to the screen-locked and screen-off state. In this embodiment of this application, a state before the electronic device switches to the screen-locked and screen-off state is not limited. For example, the electronic device may switch from the unlocked and screen-on state to the screen-locked and screen-off state in response to a screen lock operation. The screen lock operation may include but is not limited to: a press operation on a screen lock button on a side edge or a top edge of the electronic device, a tap operation on a screen lock control in a user interface, a voice instruction, a gesture instruction, and the like. For another example, the electronic device may switch from the screen-locked and screen-on state to the screen-locked and screen-off state in response to a press operation on the screen lock button on the side edge or the top edge of the electronic device or after a period of time (for example, 10 seconds).

In a possible implementation, the electronic device may set a card of the interactive wallpaper on the desktop. The card includes a screen-off control. The electronic device may enter the screen-locked and screen-off state in response to a tap operation on the screen-off control.

In some implementations, after performing S601, the electronic device may immediately perform S602 in response to a screen lock operation. After performing S601, the electronic device may alternatively first respond to the screen lock operation, then immediately respond to the screen-on operation, and subsequently perform S602.

S603: The electronic device displays the first wallpaper in a first state on the back screen.

Before displaying the first wallpaper in the first state on the back screen, the electronic device needs to enable a function of displaying the interactive wallpaper. For example, the electronic device may enable the interactive wallpaper function in the setting application, or may enable the interactive wallpaper function by using the card of the interactive wallpaper on the desktop.

In some implementations, once switching to the screen-locked and screen-off state, the electronic device immediately displays the first wallpaper in the first state. Specifically, the electronic device may immediately switch from displaying the black screen on the back screen to displaying the first wallpaper in the first state. In this way, the user can observe that the electronic device is in the screen-locked state at the moment.

The first wallpaper in the first state may be the first wallpaper in a default state preset by the electronic device, namely, the first wallpaper previewed by the electronic device. For example, for the first wallpaper in the first state, refer to the foregoing FIG. 3A, FIG. 3E, and FIG. 3G.

Because the first wallpaper is not always on display with low power consumption, considering the power consumption problem, the electronic device has a limitation on duration in which the first wallpaper is displayed. The electronic device may set preset duration in which the first wallpaper is continuously displayed without stop each time, for example, 5 minutes.

In a possible implementation, a sum of duration in which the electronic device displays the interactive wallpapers in different states each time does not exceed the preset duration. For example, if the electronic device displays the first wallpaper in the first state for more than 5 minutes and the electronic device does not display the first wallpaper in another state, when displaying the first wallpaper for the fifth minute, the electronic device switches from displaying the first wallpaper on the back screen to displaying the black screen; or if the electronic device switches, when displaying the first wallpaper in the first state for the second minute, to displaying the first wallpaper in the second state, when displaying the first wallpaper in the second state for the third minute, the electronic device switches from displaying the first wallpaper on the back screen to displaying the black screen. Total duration in which the first wallpaper is displayed is 5 minutes.

In another possible implementation, duration in which the electronic device displays the interactive wallpaper in each state each time does not exceed the display duration. For example, if the electronic device displays the first wallpaper in the first state for more than 5 minutes and the electronic device does not display the first wallpaper in another state, when displaying the first wallpaper for the fifth minute, the electronic device switches from displaying the first wallpaper on the back screen to displaying the black screen, and total duration in which the first wallpaper is displayed is 5 minutes; or if the electronic device switches, when displaying the first wallpaper in the first state for the second minute, to displaying the first wallpaper in the second state, when displaying the first wallpaper in the second state for the fifth minute, the electronic device switches from displaying the first wallpaper on the back screen to displaying the black screen, and total duration in which the first wallpaper is displayed is 7 minutes.

In this embodiment of this application, content displayed by the electronic device on the back screen after the display duration of the interactive wallpaper exceeds the preset duration is not limited. This may be black screen display or always on display. Refer to the foregoing descriptions.

S604: The electronic device receives a user operation, and displays the first wallpaper in the second state on the back screen.

In some implementations, the user operation may include but is not limited to: a tap operation, a slide operation in any direction, a two-finger zoom-in or zoom-out operation, a two-finger rotation operation, and the like.

In some implementations, when displaying the first wallpaper in the first state, the electronic device may receive a user operation, and display the first wallpaper in the second state on the back screen. For time in which the electronic device displays the first wallpaper in the second state, refer to the related descriptions of S603. Details are not described herein.

The following describes the first wallpaper in the first state and the first wallpaper in the second state in different styles by using examples.

For example, when the style of the first wallpaper is the handbag style, the first wallpaper in the first state may display a naturally drooping chain and various icons naturally connected to the chain in a simulated real state. The first wallpaper in the second state may display a wavy chain and various icons that change with the chain after the user moves the chain in a simulated real state. The state switching user operation may be a slide operation on the chain. Optionally, the second state may display a wavy chain and various icons that change with the chain after the electronic device is shaken in a simulated real state. Specifically, an acceleration sensor, a gravity sensor, and a movement sensor of the electronic device may detect whether the electronic device shakes, or whether the posture of the electronic device changes.

When the style of the first wallpaper is the animal style, the animal may be various animals, for example, a panda. The first wallpaper in the first state displays an animal picture in a first posture. For example, the first posture may include: both hands raised, both legs curled inward, and the mouth corners upward. The first wallpaper in a second posture displays a same animal picture in the second posture. For example, the second posture may include: both hands down, both legs straight, and mouth corners downward. The state switching user operation may be a tap operation on the animal picture.

When the style of the first wallpaper is the feather style, the first wallpaper in the first state displays feathers naturally spread out in the growth direction in a simulated real state. The first wallpaper in the second state displays feathers that are attached to other feathers after the user moves some feathers in a simulated real state. The state switching user operation may be a slide operation on some feathers.

In this embodiment of this application, the first wallpaper may further have more styles, and the first wallpapers of different styles may further have more states. The foregoing styles and states are merely examples for description. This is not limited.

Further, the electronic device may further display the first wallpaper in a third state on the back screen again in response to a user operation when displaying the first wallpaper in the second state on the back screen. For related descriptions of the first wallpaper in the third state, refer to the foregoing content. Details are not described herein.

Optionally, the electronic device may further detect ambient light, and display the first wallpaper in the second state on the back screen. For example, the style of the first wallpaper may be a chameleon style. After switching to the screen-locked and screen-off state, the electronic device immediately displays the first wallpaper in the first state, where the first wallpaper in the first state displays a chameleon picture with natural skin colors. Then, the electronic device detects that the current ambient light is yellow light, and displays the first wallpaper in the second state, where the first wallpaper in the second state displays a yellow chameleon picture. Further, when detecting that the color of the ambient light changes, the electronic device may further display the first wallpaper in the third state on the back screen.

Optionally, the electronic device may further detect that the posture of the electronic device changes, and display the first wallpaper in the second state on the back screen. For example, the style of the first wallpaper may be a water flow style or a multi-ball style. After switching to the screen-locked and screen-off state, the electronic device immediately displays the first wallpaper in the first state, where the first wallpaper in the first state displays a water flow or a plurality of small balls accumulated at the lower part of the back screen due to gravity in a simulated real state. Then the electronic device detects that the posture of the electronic device changes. For example, the electronic device swings left and right as the user walks, and displays the first wallpaper in the second state. The first wallpaper in the second state displays the water flow or the plurality of small balls swinging as the electronic device swings left and right in a simulated real state. For example, when the electronic device swings to the left, the water flow or the plurality of small balls in the first wallpaper accumulate toward the lower left of the back screen; or when the electronic device swings to the right, the water flow or the plurality of small balls in the first wallpaper accumulate toward the lower right of the back screen.

It should be noted that, the process in which the back screen of the electronic device switches from displaying the first wallpaper in the first state to displaying the first wallpaper in the second state is a gradually changed process, rather than a sudden change process. The user may observe that the first wallpaper is gradually switched from the first state or the second state.

Optionally, in S605, when the first wallpaper includes a first icon, the electronic device receives a tap operation on the first icon, and displays a first prompt box, where information included in the first prompt box is provided by an application indicated by the first icon.

After performing S603 or S604, the electronic device may perform S605.

In some implementations, the electronic device stores first wallpapers of a plurality of styles including icons, for example, the first wallpaper in the wallet style. In this embodiment of this application, other styles may also include icons. This is not limited.

For example, the first wallpaper of the wallet style may include but is not limited to: an icon indicting an add-to-favorites function in a system application; an icon indicting a social application; an icon indicating a camera application; an icon indicating a clock application; an icon indicating a sports application; an icon indicating a music application; and the like. In response to a user operation, the electronic device may further change the icons included in the first wallpaper.

For example, when the first icon is an icon indicating a social application, the first prompt box may include: a chat box or message prompt information; when the first icon is an icon indicating a camera application, the first prompt box may include: a most recently shot photo; when the first icon is an icon indicating a clock application, the first prompt box may include: time and date information; when the first icon is an icon indicating a sports application, the first prompt box may include: exercise step information; and when the first icon is an icon indicating a music application, the first prompt box may include: a name of a song currently played and singer's name information.

In this embodiment of this application, the forgoing first icon is merely an example for description, and the first icon may further indicate more applications. This is not limited.

In a possible implementation, after displaying the first prompt box, the electronic device may not display the first prompt box in response to a tap operation on an area that is other than icons and that is in the first wallpaper; and may not display the first prompt box in response to a tap operation on a second icon, and display a second prompt box at the same time, where information included in the second prompt box is provided by an application indicated by the second icon.

Optionally, in S606, the electronic device receives a tap operation on the first prompt box, and displays a first user interface, where the first user interface belongs to an application indicated by the first icon.

After performing S605, the electronic device may perform S606.

In some implementations, if the electronic device sets a screen lock password, the electronic device may display a screen lock wallpaper after receiving the tap operation on the first prompt box. Subsequently, the electronic device may display the first user interface after receiving an unlock operation. The unlock operation may include but is not limited to: a touch operation on a specific area (such as a fingerprint recognition area), a face unlock operation facing the camera, an operation of entering a password (such as an alphabetic and/or numeric password or a graphic password), and the like.

Specifically, the electronic device receives a tap operation or a double tap operation on the first prompt box, displays the screen lock wallpaper on the main screen, and displays the screen lock wallpaper on the back screen or makes the back screen black. Subsequently, the electronic device may display the first user interface in response to the unlock operation.

For example, when the first icon is the icon indicating the social application, the first user interface displays the chat box included in the first prompt box; when the first icon is the icon indicating the camera application, the first user interface displays the photo included in the first prompt box; when the first icon is the icon indicating the clock application, the first user interface displays the time and date information included in the first prompt box; when the first icon is the icon indicating the sports application, the first user interface displays the exercise step information included in the first prompt box; and when the first icon is the icon indicating the music application, the first user interface displays the song name and the singer's name information included in the first prompt box.

In this embodiment of this application, the first user interface is merely an example for description, and the first user interface may alternatively be another user interface of an application to which the first icon belongs. This is not limited.

Optionally, in S607, the electronic device switches from the screen-locked and screen-off state to the screen-locked and screen-on state, and displays the screen lock wallpaper on the back screen.

In the layered architecture, software is divided into several layers, and each layer has a clear role and task. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers: an application layer, an application framework layer, an Android Runtime and a system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in FIG. 8, the application packages may include applications such as Camera, Gallery, Calendar, Phone, Map, Navigation, WLAN, Bluetooth, Music, Video, and Messages.

The application framework layer provides an application programming interface (API) and a programming framework for an application at the application layer. The application framework layer includes some predefined functions.

As shown in FIG. 8, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, and the like.

The window manager is configured to manage a window program. The window manager may obtain a size of the display, determine whether there is a status bar, perform screen locking, take a screenshot, and the like.

The content provider is configured to store and obtain data, and enable the data to be accessible to an application. The data may include a video, an image, audio, calls made and answered, a browse history and a bookmark, a personal address book, and the like.

The view system includes visual controls such as a text display control and a picture display control. The view system may be configured to construct an application. A display interface may include one or more views. For example, a display interface including a message notification icon may include a text display view and a picture display view.

The phone manager is configured to provide a communication function for the electronic device 100, for example, management of a call status (including answering, declining, or the like).

The resource manager provides various resources such as a localized character string, an icon, a picture, a layout file, and a video file for an application.

The notification manager enables an application to display, in the status bar, notification information, which may be used for conveying a notification-type message that may automatically disappear after a short stay without user interaction. For example, the notification manager is configured to: notify download completion, give a message notification, and the like. The notification manager may alternatively be a notification that appears in a top status bar of the system in a form of a chart or scroll bar text, for example, a notification of an application running on the background or a notification that appears on the screen in a form of a dialog window. For example, text information is displayed in a status bar, a notification sound is given, the electronic device vibrates, or an indicator light blinks.

The Android Runtime includes a core library and a virtual machine. The Android runtime is responsible for scheduling and management of the Android system.

The core library includes two parts: a function that needs to be called in java language and a core library of Android.

The application program layer and the application program framework layer run in the virtual machine. The virtual machine executes java files at the application program layer and the application program framework layer as binary files. The virtual machine is configured to execute functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The system library may include a plurality of functional modules. for example, a surface manager, media libraries, a three-dimensional graphics processing library (for example, an OpenGL ES), a 2D graphics engine (for example, an SGL), and the like.

The three-dimensional graphics processing library is configured to implement three-dimensional graphics drawing, image rendering and synthesis, layer processing, and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, and a sensor driver.

The following describes working procedures of software and hardware of the electronic device 100 by using examples with reference to a photo capture scenario.

When the touch sensor 180K receives a touch operation, a corresponding hardware interruption is sent to the kernel layer. The kernel layer processes the touch operation into an original input event (including information such as coordinates of touch and a timestamp of the touch operation). The original input event is stored at the kernel layer. The application framework layer obtains the original input event from the kernel layer, and identifies a control corresponding to the input event. Using an example in which the touch operation is a touch tapping operation, and a control corresponding to the tapping operation is a control of an icon of the camera application, the camera application invokes an interface of the application framework layer, and the camera application is started, so that a camera driver is started by invoking the kernel layer, and a static image or a video is captured by using the camera 193.
